YAP 502 - Deformation Properties of Materials

Course Objectives

1- Understanding of strain stress behavior of the materials having different characters in cause and effect relation.
2- Teaching of the differences of material behavior in relation of atomic structure.
3- Evaluation of engineering properties of materials and the effective parameters on these properties.
